To a/ZZ whom t may concern:

Be it known that I, EDWIN CARVER, a citizen of the United States,residing at Winchester, in the county of Randolph and State of Indiana,have invented certain new and useful Improvements in Machines for MakingPlugs for Paper-Rolls, of which the following is a full, clear, andexact specification.

My invention comprises improved means for advancing the material to beoperated on, improved means for boring out the center of the plugs andfor forming the exterior of the plugs, as well as the means for severingthe completed plugs from the source of supply.

Other objects and particular advantages of my machine will be madeapparent in the course of the ensuing specification.

One manner of carrying out this invention `and that which in practicehas been found to companying drawings, in which- Figure 1 is a plan viewof my entire machine. Fig. 2 is a front elevation of the mai chine. Fig.3 is a right-hand end view thereof.- Fig. 4 is a left-hand end viewthereof.

Fig. 5 is a central longitudinal sectionof the machine'as taken on theline X X of Fig. 1. Fig. 6 is a cross-sectional view ofthe machine astakenon the line Y Y of Fig. 1. Fig. 7 is a detail view of the means foractuating the lateral movements of the bit and knives. Fig. 8 is adetail plan view` of same. Fig. 9 is a detail view oi the means forreleasing the material during the time the machine is being fed forwardand for holding it during the time it is `being acted on. Fig. 10 is adetail isometrical view of the product as formed and completed by themachine. Fig. 11 is a4 detail face view of the feed-operating cam. Fig.12 is a detail showing an edge view of the feed-operating cam. Fig. 13is a detail of one of the identical rollers for the ratchet, and Fig.v14 is a detailview of the ratchetdisk.

Similar indices refer to and denote like parts throughout the variousviews of the five sheets of drawings.

In order that my invention and its intend- `ed operation may be morereadily under- 4an especially-designed body or table A, having theperfectly level bed-plate a, and it is supported and carried on fourlegs Aand A anda and a, all of the other devices being carried by saidparts and located substantially as shown in the drawings. Between thelegsA and A is a web carrying the bearing B, and between the legs a anda is a web carrying the bearing C. Mounted longitudinally ofthe machineand carried in said bearings B and C is the main shaft D, on which shaftare mounted various cams and other parts, which will presently beexplained. End movement of the shaft D is prevented by the two collars Eand E', which are located adjoining the outer ends of the bearings B andC, respectively.

Forming mechanism--Mounted on the bed-plate a are the two standards 1and 2, right and left, respectively, having mounted on their uppercentral portions the respective bearings 3 and 4, in which bearings thehorizontal operating-shaft 5 is revolubly and slidably endwise mounted,and said shaft 5 extends across between said bearings and projects tothe right and left thereof, as shown. Extending centrally andlongitudinally through the shaft 5 in an axial direction is a circularaperture to receive therod,

loosely slidable therein. At the left-handl end of the shaft 5 the mouthof said aperture is enlarged, from which it tapers to the rightconvergingly and joins the uniform aperture, which extends the balanceof the distance to the right-hand end of the shaft 5; Contained in saidtapering portion of said aperture is a split clamp 7, having itsright-hand end secured to the left-hand end of said rod 6. In the clamp7 is a space formed in an axial direction to receive removably the bit8. vSecured around the left end of the shaft 5 is the head 9 forcarrying the detachable knives H and I. The said rod 6 is threaded onits projecting right-hand end to receive the nut 10, whereby the clamp 7may `be drawn to the right to cause it to tightly clamp the bit 8 and bywhich the bit 8 is held in the position shown. Secured on the shaft 5,between the bearings 3 and 4, is the pulley 11, provided to receive anindependent belt thereover, whereby it is connected to the power-pulley.(Not shown.) By the above it is apparent that the shaft 5, carrying thebit and the knives, may be revolved at the desired rate of speed.Mounted on the right- IOD 1 hand end of the shaft 5 is a collar 12, inwhich the shaft revolves and the purposes of which collar will presentlyappear. f

The numerals 13 and 13 denote each a rod which are of identicalconstruction mounted for horizontal endwise movements, being carried inapertures formed in the end of the frame A to provide bearings and withtheir left-hand portions carried in bearings formed therefor in thespider 14, which spider is suspended between the sides of the body A.

The numeral 15 denotes the vertically-disposed standard pivoted at itsupper end to the collar 12, then extending downward, dividing into twobranches, each being secured by screws to the outer ends of the rods 13and 13, substantially as shown.

Connecting the inner ends of the rods 13 and 13 is the spider 16, andextending down through the center of the spider 16 is the pivot-bolt 17,which carries revolubly thereon the roller 18. Mounted on the shaft D isa double cam composed of the right and left members J and K,respectively, and which are of substantially identical construction, andthey are spaced apart sufficient to allow the roller 18 to passtherebetween. Mounted on the outer right-hand end of the shaft D is thepower-pulley L, having an independent belt extending to a line-shaftpulley. (Not shown.) It will now be apparent that the formation of thecam J K is such that when the pulley L is revolved the said cam willalternately move the rods 13 and 13 to the right and left, and therebythe shaft 5 will also be carried to the right and left at eachrevolution of the pulley L, as a consequence operating the bit 8 and theknives H and I to the rightand left. v

Feed mechanismpLocated on the lefthand end of the bed-plate a is thefeeding mechanism, which I will now specify. This consists first of abase-plate 20, adjustably mounted on the bed-plate by four adjusting andsecuring screws 21, 22, 23, and 24, whereby the base-plate 20 may beadjustably secured vertically to the height desired for varyingconditions. Mounted on the plate 20 are the two hangers or standards 25and 26, spaced apart and secured each by a pair of machine-screws 27 27and 28 28, respectively. Thel center portion of the hangers 25 and 26extend upward and downward with vertical guideways 19 and 29,respectively, formed therein, as shown. Mounted in the lower portions 0fthe guideways 19 and 29 are the respective guide-blocks M and N, in andbetween which is mounted the shaft 30. The guide-blocks M and N and theshaft 30 are adjustable by the set-screws 31 31, which extend up frombelow. Central of the shaft 3() is the V-faced roller 32. Extending tothe left from the center of the plate 2O is the finger 33, having itsextreme left end curved upward and divided, with a V-faced roller 34mounted therein, which roller is identical with and alined with the saidroller 32.

Mounted in the upper portion of the guideways 19 4and 29 are therespective guideblocks O and P, (similar to the said guideblocks M andN,) in and between which is mounted the shaft 35. Mounted on the shaft35 between the guide-blocks O and P, is the large V-faced feed-wheel 36,the V-face of which is knurled or serrated to produce a biting-surfacetherearou-nd, as indicated, and being oppositely disposed to the saidrollers 32 and 34. Extending up to near the height of the said guideways19 and 29 are the relatively long guide-screws 37 and 37 their lowerends being screwed into hangers 25 and 26, and each having a pair ofnuts 38 and 38 in front, and 39 and 39 in rear, which are threaded ontheir upper ends. The numeral 40 denotes a lever having the forkedextensions 40a and 4Gb, the free ends of which are given a quarter-twistwith a slotted aperture in each endto receive the bolts 37 and 37', asshown, whereby the forks or arms 40a and 40b are loosely mounted betweenthe respective pairs of nuts 38 38 and 39 39. The said forks 40a and 40bare adapted to rest on the inwardly-projecting portions of theguideblocks O and P, to which they are loosely held in contact by therespective guide-fingers 41 and 41, whereby it is apparent that thefeed-wheel 36 may be raised and lowered by the operation of the lever40. The pressure downward on the feed-wheel 36 maybe varied by means ofthe weight 42, which weight is adjustable along the length of the lever40 and -is securable at the point desired.

Raw 'material-The material to be su plied to this machine for operationon shou d consist of any suitable lengths of timber, substantiallysquare in cross-section, as is indicated in Fig. 4, where it isdesignated by the letter R, and said material is to be fed into themachine endwise from the left-hand end of the machine between the lowerrollers 34 and 32 and under the upper feed-roller 36.

Operation of the feed-The next construction l will describe is the meansfor automatically feeding the material R into the machine, where itis tobe operated on. Mounted permanently on the shaft 35, just forward of theguideway 29, is the barrel or drum 43, and neatly fitting the interiorof the said barrel 43 and mounted Within the barrel revolubly on theshaft 35 is the disk 44, neatly filling the interior of the barrel. Thesaid disk is held in place in the barrel by the nut 45, which isthreaded on the end of the shaft 35, as shown in Fig. 2, and the saiddisk and the face of the barrel may be closed by a cap or plate 95, ifdesired. Said cap 0r plate 95 is removably screwed to disk 44 by screws,as shown, and held to the face of the barrel by nut 45, so as to inclosethe disk 44. Cut into and out of the regular rondure of the periph- IOOIIO

25 connecting-rod 48.

iery of the disk 44 are the two tapering indentations S and S ofidentical size and form, which extend across the thickness of the disk'l and are of substantially the contour shown. The indices 46 and 46denote a pair of iden- \ti`ca'l plain rollers of same length as is thethickness of the disk 44 and of a diameter less than the larger end ofsaid indentations S and j S and greater than the smaller end of same. 1o'By the employment of the mechanism just described it will be seen thatthe disks 44 will be free to revolve to the right independent of thebarrel 43 but when revolved to the left the rollers 46 and 46 will wedgebetween the small ends of the respective lndentations S zo wheel 36 in adirection such as to feed the material properly into the machine.Projecting out from near the periphery oi the face of the disk 44 is thecrank-pin 47, on which is mounted the left-hand end of the Mounted onthe front portion `of the end of the body A is a hangerblock 49, havinga pivot T, on which is pivoted the lever 50, the upper half of which hasa longitudinal slot'U therethrough, as shown in ,3o Fig. 2.

The numeral 51 denotes a bolt mounted in the right-hand end of the rod48 and through the slot U, whereby the end of the rod 48 may bepivotally connected to the lever-arm 3 5 v50 at any point verticallywithin the limits of the slot U.

Mounted on the shaft D, over the pulley L and the right-hand end of thebody A, is the cam 52, having a depression into its left-hand 4o face,on which face the roller 53 is adapted to travel. Said roller 53 ismounted on the lower' end of the lever 50 by the pivot-bolt 54. Ahelicalcompression-spring 55is mount- V ed to press out between the lower endof the lever 50 and the end of the body A, as shown i'n Fig. 2. It willnow be apparent that as the shaft D is revolved, the roller 54 beingkept in contact with the face of the cam 52 by the spring 55, as theroller 53 is caused to 5o move alternately to the right and left theupper end of the lever will be moved oppositely thereto and with agreater latitude, thus operating to turn the feed-wheel 36 step by stepthe proper distance at the proper 55 time, this being adjustable bymeans of the slot U, as shown.

MctericZ-cZamp.-The left-hand portions of the hangers 25 and 26 extendupward with the vertical guideways 56 and 57 formed 6o therein,respectively, as shown. Extending across with the ends carried in saidguideways 56 and 57 is the clamp-bar 58, which has a centralinverted-V-shaped notch to engage the material and having its ends pro-.turned forward at right angles thereto.

ject through `and beyond the guideways 56 and 57, with vertical eyesformed through said outer projections to receive the upper ends of therods 59 and 60, which are secured in said eyes by a pair of lock-nuts,as shown. Said rods extend down and slide loosely through aperturesformed in the ears 61 and 62, which project out from the left-handcorners of the plate 20. The lower end of the rods 59 and 60 areconnected by the yoke 63, to which they are secured by lock-nuts, asabove and as shown. Extending down from the center of the yoke 63 is thehanger 64, in which is mounted the roller 65. Mounted on the shaft D isthe cam 66, around the peripheral face of which the roller 65 is adaptedto travel and by which the clamp-bar 58 is raised and lowered'at theproper time to engage and release the material. The roller 65 is kepttightly in contact with the cam 66 and the clamp-bar 58 in contact withthe ina-k terial by the two coil-springs 67 and 68, which surround therespective rods 59 and 60 and are seated against the ears 61 and 62,respectively, substantially as shown.

I ntermedt'a/ry material remmen-Secured centrally of and on top of theclamp-bar 58 is the flat spring 70, which curves to the left and then tothe right, terminating some distance immediately below the center of theclamp-bar 5,8 and having a lterminal end adapted to at all times engagethe upper corner of the material, which may be in the machine and fromwhich it does not release by the movements of the clamp-bar 58, to whichit is attached, as shown.

The sawing mechanism-Mounted hori- IOO zontally and having its front endsecured to the rear of the bed-plate by two pairs of bolts 71a and 71band extending rearward therefrom is the permanent stationary table 71for supporting the saw-carriage. Slidably mounted on the table 71, andmounted only for forward and backward movements thereover, is thesaw-carriage 72, (preferably mounted on frictionless bearings, notshown.) Rising from the said carriage is a pair of pedestalhangers 73 73in which is revolubly mounted the saw-shaft 69 on which shaft thecircular saw 74 is mounted, adjoining the outer face of the hanger 73,as indicated. Mounted on the shaft 69, between the hangers 73 and 734,is the belt-pulley 75, from which a belt may extend to its drive-pulleylocated directly above. In the permanent table 71 is a centrallongitudinal slot, through which pass the downwardly-extending arms 76and 77, which arms are united at their lower terminals and terminate ina finger 7 8,which is The upper end of the arm 76 is secured to thecarriage 72 by the bolts 7 6a and 76h, and the upper end of the arm 76is secured to the carriage 72 by the bolts 7 7at and 77h. Mounted IIO onthe shaft D is the side-faced channel-cam 80, and mounted on the end ofthe finger 7S is the side-mounted roller 79, which is adapted to travelin the channel 80, as shown, whereby as the cam revolves, thesaw-carriage will be moved forward and backward at proper intervals. l

Product and refuse conceyers--The numeral 8l denotes a square anddownwardly and thence rearwardly extending spout or conveyer for thefinished product, which is carried forward and backward with and by thesaw-carriage, which conducts the finished product to the rear of themachine. Said conveyer is secured to the finger 7 8, as shown, while atie 81 connects its central portion rigidly parallel with the arm 76.The upper end of said conveyer, when the saw is drawn to the rear, isclosed by the permanently-located cover SS-that is, when the saw is outof action. Secured to the front of the spout 81 is a downwardly andforwardly extending deflector 84 for the shavings and refuse which fallsfrom the knives and bit to be defiected forward.

The product-The numeral 85 denotes the .finished product, which isclearly indicated in Fig. 10, and it is designed particularly for use inrolls of paper or the like; but as to the product I make no claim.

Operation-It will be noticed that power is applied to this machine atthree independent points by the pulleys L, 11, and 75, the two formerrevolving to the right while the latter revolves to the left. Themachine is therefore geared to accomplish three distinct and independentoperations, which may follow each other in progressive and propersequence, and, if desired, the operations may overlap each otherthat isto say, one operation may begin before the completion of the other. Thethree operations naturally consist in, first, the feeding of thematerial and holding it while it is being fed; second, the boring andcutting the plug, which includes the approach and the withdrawal of theknives and the bit to and from the material, and, third, the completingof the plug by sawing it from the supply, In the drawings the machine isillustrated during the firstnamed operation. As the shaft D continues torevolve, the contour of the cam 52 is such that the feed-wheel 36 willremain stationary and the contour of the cam 66 is such that theclamp-bar 58 will engage and hold lthe material in its advancedposition, which would be with the end of the material advanced to nearthe point of the receded bit 8. At this point the cam J K will haverevolved to the point that it gradually causes the bit to be forced intothe center of the forward end of the material to form the centralopening in the to be finished plug, at the same time the shaft 5 beingcontinuously revolved to revolve said and 'also to revolve the kniveswhereby the periphery of the plug is formed, as shown. As the bit andknives complete their work, they are, by means of their cams,withdrawnto the right,iand during the last stage of the last-namedoperation the cam 80 will have revolved to the point where it willgradually, but swiftly, move the sawcarriage forward, whereby the teethof the swiftly-revolving saw 7 4 will be brought into contact with thematerial at the point to which the plug 85 is completed, the same beingthe larger end thereof, whereby the plug will be completed and severed,falling down through the spout S1 to the rear of the machine, as whenthe plug is being formed the chips therefrom fall in front of themachine.

Having now fully shown and described my invention and the best means forits construction and operation to me known at this time, what I claim,and desire to secure by Letters Patent of the United States, is Y 1. Ina machine for making plugs for paper-rolls, the combination with meansfor alternately lfeeding endwise and holding a rod, cutters shaping theend portionthereof and a reciprocating cutting-off tool arranged andtimed to sever the portionso shaped, of a spout or receiver travelingwith said cuttingoff tool and advancing to a position under-the portionbeing cut off to receive the same-and a fixed cover for said spout, to aposition under which it returns in order to exclude the chips producedby the shaping-cutter, all substantially as shown and described.
